Rough Country AT4 level kit

Trailboss75 · June 18, 2019

While I have a Trail Boss and not an AT4, just thought I would share this. Looks as though Rough Country has put out an official level kit for the AT4.

Of course. Right after I install the motofab 1.5

haha, yeah I have the 1" Motofab, but figured it would be temporary until I see what they officially come out with for a level kit for the TB. I am sure Ready lift will release theirs soon as well.

Whole different leveling setup than the standard lower key that many have tried using on the AT4 and Trail Boss.

Which was my point in another thread where a member was having issues.

There was a reason after all that this style of leveling kit took so long to be introduced.

Proper research and development is the key to engineering success

I’m curious to know what the difference is with the AT4 Kit vs Trailboss Kit. Anyone have an idea?

yep, I agree, although I did put a 1" motofab (motofab recommended lift) as a temporary fix for bigger tires until the proper lift came out. definitely a lot different lift than the standard lower strut spacer.

Problem was with the guys who were installing the 2" lift key on their Trail Bosses /AT4s

This Rough Country kit is definitely not that! LOL

What exactly is the RC kit? How does it differ from the puck style?

I'm curious as well!

Looks like a lot of work, for a little lift.

Just read the instructions... Looks like RC is using a spacer in the strut spring and another under the lower mounts. so essentially 1" up top and 1" below.... I don't see the significance in this over 1.5 / 2" spacer below the strut...

Plenty of installs with the standard level kits being used since the AT4 came out and yet to see any poor reports. If it turns out later there are issues w upper ball joint angles, then newer upper control arms can be added. ( I did this on my 2013 2500 a few years ago. )

So far it seems that the standard levels kits work,... But no feedback and I suspect we wont get any...

My dealership has a couple of AT4s on the lot that are leveled. I called and asked about a dealer installed front level and voiding my warranty. The dealer wants $875 to install the level / alignment, and says it will remain under full factory warranty. The part number they game me is Pro Comp 63235. Pro Comp's website says this part is not for the AT4. Any thoughts? I have not raised this to my dealership yet, as I am working for a couple more weeks before I will be home to install anyway.

If you are mechanically inclined and have a jack stand and floor jack you can do this yourself and save $$... or buy the parts and have a local shop do it...for less than dealer... its an 1 to 1.5 hrs of work then alignment...

Most of the level kits being installed are " not for the AT4" but they work as is shown by the number of members doing installs..

I'd be curious the dealers response to the pro comp not being AT4 compatible... but as mentioned they work...

In order to void a warranty it has to be proved that it caused a failure... I'm running the readylift 2" level kit and 3" blocks rear...

Good luck

I installed Motofab's 2" level myself on my 2017. I am very mechanically inclined and had no issues during the install. Loud popping noises started while turning after about 1,000 miles. I also had both lower control arms come loose (bolts not even hand tight) twice. The control arm bolts were not touched during the install. The dealership and two local accessory shops chased the popping noise for 30,000+ miles until I traded the truck. They continued to tell me everything was correct, and they could not locate the source of the noise.

I am paying the dealership if I level my AT4, and it will be under factory warranty this time.

With that being said, I have personally put eyes on three AT4s currently on the lot with dealer installed level kits. I guess this is the option for me, but my main question was about the kit they are using not being rated for the AT4 by the manufacturer. I think you have cleared it up for me.

thsoccer3 · June 26, 2019

Here is my research:

1). Dealer installed Pro Comp 63235 for $875. Dealer says they will stand by factory warranty if they do the work, but Pro Comp says this kit is not rated for the AT4.

2). Local accessory shop installed Rough Country Sku: 1318 for $350. If the dealer were to void warranty because of this mod, RC's website fine print says the owner is responsible for having a dealership fix the truck, and then contacting Rough Country to prove the malfunction was caused by the lift kit. This raises caution and sounds like the beginning of a "blame-game" or "run-around" to me.

My end goal is to level the front and go with 295/65/20 (35.1") or 295/60/20 (33.9") Nitto Ridge Grapplers, but my concerns are warranty and sacrificing ride quality.

Any thoughts?
